Found on a blackboard at the University of Chicago

I found this list of what is supposed to be the future winners of the Nobel Prize in Economics on a blackboard at the U of C, for what it is worth. Who knows whether the people who made the list know what they are talking about. There are about 40 people on the list, and about 2 people get . . .



Sumo in Vegas

Most of the events described in Freakonomics took place, or still take place, in the continental U.S. — except for the chapter describing how sumo wrestlers collude to throw matches. We’ve gotten a surprising number of e-mails from readers in Japan with interesting sumo comments but most of us don’t have regular access to live sumo. At least we didn’t . . .




Lojack for Bikes?

Several years ago, Steve Levitt and Ian Ayres wrote a paper about Lojack, the silent anti-auto-theft device. They found that crime theft falls overall in areas where even a small percentage of the cars carry Lojack. I got to thinking about Lojack when we received this e-mail the other day from a reader frustrated with the volume of bicycle thefts . . .



Freakonomics in the Times Magazine: Dog-Waste Management

The October 2, 2005, Freakonomics column appeared in the annual New York City issue of the New York Times Magazine. In keeping with the Freakonomic tenet that few topics are too trivial for dissection, Dubner and Levitt turn their attention to the essential New York City issue of dog poop. Click here to read the column. This blog post supplies additional research material.



Oh, Poop!

Our latest New York Times Magazine column, appearing in the Oct. 2 issue devoted to New York City, concerns a long-standing problem: dog poop. We propose a fairly novel solution. And, as always, we’ve posted a page full of supplemental information, some of it inevitably more interesting than what ends up in the column.



Crime vs Crime Rate

A host of commenters on my Bill Bennett post get very agitated over the question of “crimes” vs. “the crime rate.” The term “crime rate” implies a denominator, typically “per 100,000 residents.” So the number of crimes can fall, but the crime rate can rise if the population shrinks. Bill Bennett said, “But I do know that it’s true that . . .



Freakonomics on TV Again

On Friday, Sept. 30, ABC’s “World News Tonight” (6:30 p.m. Eastern) will feature a segment on Freakonomics, the first of what may be several such segments. The ABC website goes so far as to declare today “Freakonomics Friday.” Linda Jines, who is Steve Levitt’s sister and who came up with the title Freakonomics, should feel especially proud of herself today.



Bill Bennett and Freakonomics

Bill Bennett and I have a fair amount in common. We’ve both written about crime (his “superpredator” theory gets a quick discussion in Freakonomics), we have both thought a lot about illegal drugs and education (he was the original “drug czar” and is a former Secretary of Education), and we both love to gamble (although it seems I do it . . .



Old-school Chicago Cheating

In Freakonomics, we talk a lot about catching cheaters using data. Based on a newspaper clipping that Stephen Stigler (a well-known professor of statistics at the University of Chicago, author of a wonderful book on the history of statistics, and son of the great Chicago economist George Stigler), there is a long history of using data to catch bad behavior . . .



Freakonomics on ABC-TV

Levitt and I are scheduled to appear on ABC’s Good Morning America tomorrow (Thu., Sept. 29), somewhere around 7:30 a.m. EDT, to talk about Freakonomics. We do have a pretty dismal record of getting bumped by breaking news, so maybe we’ll never actually appear on the airwaves chatting face-to-face with the splendid Diane Sawyer — but by God, that’s what . . .



The Crystal Meth/”Purpose-Driven Life” Coefficient

Years ago, I got an M.F.A. in fiction writing, thinking I’d be one of those novel-writing university professors who wear tweed jackets with leather elbow patches. But I gave up on fiction, and here’s why. The novel I was writing at the time was about a family very much like my own. Although I knew a good bit about my . . .



Tired of waiting for hours at the emergency room?

Emergency rooms serve as the front lines in the world of medicine. Many (most?) visits to ERs are not emergencies at all, but rather, routine visits by people with limited access to health care. As a consequence, waiting for hours to be seen is not uncommon. Forced to take all patients, the ER raises the “price” by making you wait. . . .



Signed Copies of Freakonomics

March 5, 2021: These bookplates are no longer available. We’re sorry for the inconvenience.  A few days ago, we made this offer to send a signed bookplate, free, to anyone who wants one. The good news is that a whole lot of people took us up on the offer. The less-good news is that, because of the volume, it’ll take . . .



Seth (Diet-and-Acne-Guy) Roberts

The Berkeley psychologist Seth Roberts was good enough to guest-blog here all last week. A lot of people still have questions for him. He can be reached at shangriladiet@gmail.com; you can also click here to read about his research.



If You Live in NYC, You Are Invited …

… to come hear me (Dubner) give a non-Freakonomics reading, on Mon., Sept. 26, 7:00 p.m., at the Half King. It’s an event to celebrate the publication of The Best American Crime Writing 2005, an anthology that includes a New Yorker article I wrote about a cunning silver thief. (Oops: I just showed you the free version of the article . . .



Caution: We Know What You Are Thinking

We have twice blogged — here and here — about Moodgrapher, a mood-tracking site built by Gilad Mishne at the University of Amsterdam. It tracks the blog entries of Live Journal users and aggregates their mood indicators to see how a given event (a terrorist act, a natural disaster, an election) influences societal mood. Levitt proposed that corporations might employ . . .



Anybody Want an Autographed Copy of Freakonomics?

March 5, 2021: These bookplates are no longer available. We’re sorry for the inconvenience.  Once in a while, someone writes to ask if we would autograph his or her copy of Freakonomics. And we say: sure, thanks for asking. But the logistics aren’t very smooth. A person would have to mail the book to one of us, and include a . . .



News and Notes From All Over

A while back, there was discussion, only half in jest, that Levitt might make a good Supreme Court Justice. Now things have gotten even crazier: he has been nominated (again, only half in jest) by the BBC to help rule the world: click here for the opening page, then the “click to start” tab and then “Economists.” (It is telling . . .



True Genius: Kevin Murphy wins MacArthur “Genius” Award

I’ve had the chance to meet a lot of smart people in my life. Without question, Kevin Murphy is the smartest of them all. Not only is he smart, but he is also one of the kindest, most loyal, and most generous people I’ve known. So I could not be happier that the MacArthur Foundation today named him as one . . .

Planned Parenthood Gets Freaky!

For a long time, the pro-life movement has had a keen sense of how people respond to incentives. Protesters outside of clinics proved to be a very effective strategy for raising the social and moral costs of seeking an abortion. Now a Planned Parenthood clinic in Philadelphia has come up with a very clever strategy for fighting back, called “Pledge-a-Picket:” . . .

Can Crime Be Meditated Away?

Okay, how’s this for an example of crime prevention: transcendental meditation. Several years ago in Washington D.C., 3,000 people got together to meditate and … yes, drove drown crime throughout the city. That’s their story, at least. For all I know, this is an old story; it may also be totally insane. But it makes for interesting reading: click here . . .
